Disadvantages of the Mitsubishi V4A51 gearbox
- This is a reliable and durable automatic transmission, and most of its problems are purely age-related.
- The clutches of the Reverse and Overdrive packages wear out the fastest here.
- With constant use of a car off-road, the planetary gears do not last long.
- Speed sensors and inhibitor (selector lever position sensor) often fail.
- Change the antifreeze in your car regularly or corrosion will corrode the automatic transmission heat exchanger.
